Identify these little buggers

[NanotankBank]

So in my 5gal low tech aquarium, I have noticed these little things on the walls and then these other little things swimming around. I’m sure the ones on the walls are pest snails, the lady I acquired plants from said she had them, but I just wanna be sure. Also, it’s hard to get a video of the swimmers but they r super tiny and if anyone has an idea of what they might be, let me know and I’ll Google to help sure.

You can get an Assassin snail to deal with the pest snails.

Those are likely pond or bladder snails. If you like snails in your tank, they will multiply if they can find some food. If you don’t, you can squish them and give your fish a snack or remove them manually and chuck them. Have any friends with puffers or loaches? Those fish will eat them up!

In regards to the swimming thing… what does it look like? A worm, a speck, something else? How does it swim; jerky, wiggly, smoothly with purpose?

Some of them look like tiny little tadpoles. Not worms, and they kinda jerky around like strokes

More photos please!  I would say it's a flatworm potentially. Planaria?

leeches and a lot of other things swim. Planaria are flat worms that glide like snails and slugs. Don't smush planaria, they can regenerate a new being from parts. You cut a planaria into 5 part, you get 5 whole planaria. Something that looks like a tad pole could be fry. Did she have guppies? The big eyes on the tiny born guppies can look a bit like tadpoles. Keep the plants in a separate jar until you know  for sure what you are dealing with. The "reverse respiration" works like a charm, and seltzer and club soda are cheap compared to treating fish.
